This paper aims to provide an analysis of battery electric vehicle (BEV) performance based on a comprehensive collection of specifications of over 40 currently globally available BEVs. The analysis comprises dimensional, powertrain, and performance data. The collected data are provided in this paper to facilitate further academic studies. There are a wide variety of BEVs from small to large as well as high-performance sedans and sport cars. It was found that all BEVs use Li-ion batteries with a specific energy of 55-170 Wh/kg and that battery weights represent 13%-37% of the vehicle weight. Furthermore, the majority of BEVs use permanent magnet motors, where some indicate power densities of 1.5-3.1 kW/kg. The specified New European Driving Cycle (NEDC) driving range varies between 85 and 528 km, and the energy consumption between 117 and 268 Wh/km. A rough estimation indicates that the powertrain's share of the net energy consumption during NEDC may be up to around 40%-54%.
